Abstract
An arrangement for guiding on a coal bank side a coal cutting machine at a conveyor trough with guide section portions for a round-link chain which is engaged by a chain drum which drives the cutting machine. The abutting ends of the guide section portions are constructed without upper guides and have overlapping joint projections. In addition the abutting ends of the guide section portions are connected to each other through chain guide members which extend across the joint area. The chain guide members are connected through connecting bolts while maintaining a predetermined play to the trough portions, wherein the chain guide members have corresponding recesses in the area of the guide section portion which is free of upper guides.
Description
The present invention relates to a kind of on the delivery chute of chain scraper conveyer the device to coalcutter or similar mining machine guiding, this device has some moulding guide sections and coalcutter transmission mechanism of installing from the coal mining side that is fixed to the mining machine guidance type spare on the delivery chute from the coal mining side, wherein delivery chute is divided into some chute sections, and transmission mechanism has a sprocket wheel that is engaged in the ring chain.Ring chain is installed in the chain guide of mechanical guide type spare, and this chain guide comprises last targeting part that is used for the guiding horizontal chain link and the engaging groove that is used for sprocket wheel.The same place, butt end at them with the chute section of moulding guide section is connected with each other flexiblely.
People known coupling bar by means of bone shape with chute in the scope of its butt end, hingedly be connected with each other, wherein coupling bar be located at chute vertically on, the coupling bar with end thickened portion should make the chute can horizontal curvature and vertical curve.In addition, known also have interconnective with certain free gap, have a chute section to the guide plate of transported substance guiding, wherein the chute section has the chute connector of oneself, guide plate has boss in the scope of side plate end within it, and all is furnished with a junction plate by the guide plate that per two boss link to each other mutually, the junction plate eyelet that junction plate has is separated by connection strap, be used to hold two boss, they are connected plate on the one hand and surround, and with certain free gap connection strap are contained between them on the other hand.But adopt this known measure not apply decisive influence to the coalcutter chain guiding problem of relevant coal mining side.
Task of the present invention is, a kind of device that the coalcutter that starts described type or similar mining machine are led in the coal mining side is provided, in this device, even working as chute section and guide section is under horizontal curvature or the vertical curve, guiding to ring chain (round-link chain) also can make it not have the butt joint scope of passing through chute section and guide section bendingly, and it is not inaccessibility to assemble maintenance and repair work.
The present invention is this task that solves like this in this guiding device, the butt end that is adjacent moulding guide section is not go up targeting part on a predetermined length in each butt joint scope, and the movable joint lug (or hinged block) with mutual overlap joint, a movable joint lug of at least one moulding guide section is engaged in the movable joint nest of another moulding guide section.The butt end of adjacent moulding guide section is connected with each other by the chain guiding junction plate of cross-over connection butt joint scope, chain guiding junction plate links to each other with the chute section under the condition that keeps predetermined free gap by means of the coupling bar that passes the moulding guide section, and a groove corresponding to the scope of the supreme incorgruous part of moulding guide section is arranged on the chain guide edge junction plate.The result of these measures of the present invention is, can gently always not have bendingly as the ring chain of the driving-chain of the coalcutter that is directed in the coal mining side and leads in the butt joint scope of chute section and moulding guide section.In this respect, the present invention is from following opinion, promptly in the butt joint scope of moulding guide section can abandon on the predetermined length range to ring chain with and horizontal chain link guiding on targeting part.Owing to be provided with one section interruption section that goes up targeting part according to the present invention, when chute section or moulding guide section horizontal curvature and/or vertical curve, also avoided the bending of chain.Like this, the butt joint scope improves the application life of ring chain as blunt.In addition, because targeting part interrupts section on having in the butt joint scope of chute section or moulding guide section, thus not inaccessibility ring chain.This also is favourable for assembling, maintenance and repair work, especially can seal link near chain.In addition, because the movable joint lug of mutual overlap joint is arranged, realized that the movable joint with positioning action connects (or being articulated and connected), this connection covers the butt joint slit of adjacent chute section simultaneously, thereby has stoped spilling of thin buckwheat coal.In this, the present invention suggestion, the overlap joint movable joint lug of another moulding guide section holds in the mode that has positioning action between the adjacent butt end of it and chute section or that movable joint lug that is engaged in the movable joint nest is installed.
The following describes further feature of the present invention.The present invention's suggestion, movable joint center (or link center) is arranged in the base plate plane of chute section.It also is to keep alignment mutually that the Butt Section of realizing these base plates had thus both made when the chute section is crooked, therefore prevented duff from last reversion section through the reversion section down.Stipulate that in addition the groove in the scope of the supreme targeting part of the Butt Section of moulding guide section and the chain guiding junction plate is overlapping (aligning) concave arc structure, this concave arc section is distributed in the top at movable joint center.In this manner, because the conveyer chain that moves above the movable joint center and the ring chain that is used for the transmission coalcutter of setting, chute section and moulding guide section are crushed on the base plate all the time.The most handy spring steel of chain guiding junction plate is manufactured.So especially, make the horizontal curvature ability optimization of chute section and moulding guide section, this horizontal curvature ability exists in the scope of chain guiding junction plate already because the free gap of coupling bar is arranged.Coupling bar is bolt preferably, and connects lower support on the moulding guide section in the middle of the dividing bush of the slotted hole that passes chain guiding junction plate.Be implemented in when drawing in coupling bar the moulding guide section thus and can between chute section and chain guiding junction plate, do not live by kayser, but keep the activity of its horizontal curvature and vertical curve.On the whole, because mutually the movable joint lug of overlap joint and flexible chain guiding linkage section, at the moulding guide of ring chain and realized all for the chute section that also a kind of flexible movable joint connects or is articulated and connected.Contrast only shows the accompanying drawing of an embodiment to the more detailed explanation of the present invention's do below.
The schematic plan view of the part of Fig. 1 delivery chute wherein has the chain guidance type spare and the coalcutter of coal mining side;
The partial side view of content shown in Fig. 2 Fig. 1 promptly is arranged in the lateral view of the butt joint scope of two moulding chute sections and moulding guide section;
